A method of tunneling a data packet through a network communicatively coupled to a datacenter is provided. The datacenter is uniquely addressed within the network. The datacenter has a different internal address space than the network. Transformation rules are recorded for a programmable packet filter in the datacenter. The data packet is received in the programmable packet filter of a host computing device in the datacenter. The received data packet is converted in the programmable packet filter of the host computing device between a stateless tunneling data packet and a datacenter data packet according to the recorded transformation rules. The datacenter data packet is uniquely addressed within the internal address space of the datacenter. The received data packet bypasses any virtual machine processing in the host computing device during the converting. The converted data packet is transmitted from the programmable packet filter in the datacenter.
